Next November, 30th at my Civil Engineers School we’ll enjoy a very interesting speech of Julio Martínez Calzón [wikipedia, ES] of MC-2. He’s currently one of the best Spanish civil engineers, he has a very impressive (technical and artistic) work in structural design.
Torre Collserola (From Wikipedia.es, under GFDL License)
He worked in the 70-80′s with José Antonio Fernández Ordóñez (JAFO) building bridges, but he has a lot of works about another structural types. More than 10 years ago I was lucky of attending another speech where he talked about built-on-the-ground-and-up structures, and he showed three great examples: the Collserola Tower and the sports dome Palau San Jordi in Barcelona, and the Congress Palace in Salamanca.
